Radiation complications in edentulous patients

Area of Science:

• Oncology
• Oral and Maxillofacial Surgery
• Radiology

Background:

• Head and neck cancer patients often require radiation therapy, which can cause significant oral complications.
• Complete dentures are frequently used to restore function and aesthetics post-radiation.
• The risk of oral complications associated with denture use after radiation is a critical concern.

Purpose of the Study:

• To evaluate the incidence of osteoradionecrosis and soft tissue necrosis in patients wearing complete dentures after head and neck radiation therapy.
• To identify patient factors associated with the development of these complications.

Main Methods:

• A cohort of 88 patients received complete dentures after completing radiation therapy to the head and neck.
• Patients were followed for at least 6 months post-denture delivery.
• Data on prior dentition status (edentulous vs. dentulous with extractions) and complication development were collected.

Main Results:

• Three patients (3.4%) developed osteoradionecrosis directly related to their dentures. These patients were previously dentulous and had undergone extractions.
• None of the 58 edentulous patients developed osteoradionecrosis.
• Five patients (5.7%) experienced soft tissue necrosis secondary to denture use.

Conclusions:

• Complete dentures pose a risk of osteoradionecrosis in previously dentulous head and neck radiation patients, particularly those with extractions.
• Edentulous patients receiving dentures after radiation therapy appear to have a lower risk of osteoradionecrosis.
• Soft tissue necrosis is another potential complication of denture use in this patient population.
